The oiletube or Cylinder 3 is provided et lower end, directly opposite the pipel 4,

A bifurect l? streddles the upper end of oontaet plete l5 and is connectecl with foot bi'eke i8 through tbe medium of flexible conductor and .insulated clump 1d EN., respectively. A tliiril conducto? 'ends depending bracket 20' ien Clamp 20 normally nests betieiy 22 which is suitably supporti tine machine.

'The numeral designates the siga/iai horn which is connected to the battery 22 by conductor 24 enclblows when the oil in tbe oil bose reaches e low enough level to nte-eci renienisliing;- and continues to operate until ie oil is ieplenisheol. However, when the foot bmke 18 is in use, the clump 2O is flisengagee fiom the depending bracket 20" will be obvious 'when tbe circuit will be en, even though the 'Float is in engageh "pose oi" giving on alarm o1: signal ofi in the oil base reaches e low to equire lepenisliingis to from being burned out oi oil.

Having .described my invention, what If claim as new and desire to secure by Letters;

Patent is A 10W-levels.` oil signal for automobiles.-

comprising anzfzfaudible signal, a source of electrical energy, a vertically disposed oily' tube or cylinder communicating with the oil Ibase of the machine, a floatvali'fe Working in said tube or cylinder, electrical connections including a Contact extending into the lower end of the oil tube for establishing an electric circuit through the signal to loperate the saine when the float descends to a v."'uficient extent to engage said contact, a *foot brake anda movable contact connected with said foot brake for breaking the circuit when the foot brake is in use.

` In testimony whereof I affix my signature.
